SPECIFICATION forming part of Letters Patent No. 308,212, dated November 18, 1884.

Application led July 3l, 1883. (Model.)

To @ZZ w/wm it may con/cern..-

Be it known that I, EBEN T. STARR, ofthe city and county of New York, `in the State of New York, have invented a new and useful Improvement in Locks, of which the following is a speciiication.

My invention is particularly applicable to trunks, boxes, valises, and the like; and the object of the invention is to provide a very strong and secure lock, which may be secured by means accessible only from the interior of the trunk, box, or valise.

The lock consists, essentially, of a haspplate and hasp adapted to be secured to the lid or cover ot the trunk or box, or to one of the parts to be secured together, and a lockcase and lock mechanism adapted to be secured to the body of the trunk or box, or to the other of the parts to be secured together.

The invention consists in a novel manner of securing the hasp-plate and lock-case to the lid or cover and body of the trunk or box, in a novel manner of securing the hasp to the hasp-plate, in a novel construction of the hasp and lock-case, and in a novel construetion and manner of combining the locking devices which secure the hasp when locked, all ofwhich features arehereinafter described,and referred to in the claims.

- In the accompanying drawings, Figure l is a sectional view of the entire lock and portions of the parts which are secured together by it. Fig. 2 is a front View of the hasp and hasp-plate. Fig. 3 is a front view of the lockcase with its attached bolt. Fig. 4 is arear view of the lock-case with the back plate removed so as to expose theloeking mechanism, and Fig. 5 is a transverse section on the line .fr a?, Fig. l.

Similar' letters of reference designate corresponding parts in all the iigures.

A B designate the two parts which are to be secured together, and which may be respectively the lid or cover and the body of a trunk, valise, or box. The hasp and haspplate are attached to the lid or cover A, and the lock-case is attached to the body B.

C designates the hasp-plate, which, as represented, overlaps the iront of the lid or cover A, and has a hub or cylindric portion, a, which fits an opening, b, in the lid or cover. In the front ofthe hasp-plate C is a recess, c, here shown as undercut or dovetailed at the edges; and D designates the hasp,which fits insaid recess and has similarly dovetailed edges. The edges of both the recess c and hasp D might be square instead of dovetailed.

-The hasp D is secured to the hasp-plate C by a pivot bolt or pin, E, here shown as having a conical head fitting a correspondingly conical hole in the hasp, and extending through the hasp-plate. At the back or inside of the lid or cover A is a back plate, C; and e designates a screw which passes through the back ofthe plate C and screws into the end of the pivot bolt or pin E. that the pivot bolt or pin E and the screw e secure the hasp to the hasp-plate and the latter to the lid A. This means of securing is very advantageous because of its strength, and because, the screw e being accessible only from the interior of the lid or cover, the hasp or hasp-plate cannot be surreptitiously removed.

Vhen the hasp-plate is secured, the pin or bolt E bears at its inner end against the back plate C, and as the hole in the hasp D is slightly larger than the head of the said pin or bolt, play is afforded between the two, as shown in Fig. l, and the hasp may shift slightly in a lateral direction to engage with the lock-case. Because of the play between the hasp and the head of the pin or bolt E, the hasp would be liable to rattle, and to prevent this I may secure on the inner side oi' the hasp a spring, j', the upper end of which bears against the head of the bolt E, and is deiiected inward when the screw e is tightened, as shown in Fig. l. The pressure of this spring upon the bolt-head prevents the hasp from rattling.

In order to prevent the pin or bolt E from turning when the screw c is inserted or removed, I provide t-he said pin or bolt with a groove, e', which engagesaprojection, e?, in the hole in the hasp-plate, as shown in Fig. l.

F designates the lock case, which is here shown as of circular form. It fits in an open ing, b, in the body B, and has a iiange, f/,

' which overlaps the exterior of said body. It

is closed at the back by a plate, F, which may be secured by screws g', and is clamped to the body by a plate, F2, which overlaps the interior ofthe body, and is secured to the case by Hence it will be seen` lOO screws g. I-Ience it will be seen that the means from the interior of the body, and cannot be tampered with from the exterior.

In the front of the lock-ease F is a recess, 71, the edges of which are preferably dovetailed, and the hasp D, with its dovetailed edges, enters this recess when the lid or cover Ais closed. Even if the lock-ease and thehasp are not exactly in a vertical line, the hasp will readily enter the recess 7L when thelid or cover A is closed, because the end of the hasp is taper or rounded, and because the hasp can turn slightly on its securing pin or bolt E, as before described. 'The hasp-plate C and lock case F can both turn in the parts to which they are secured to adapt themselves to the position of the hasp. XVhen the hasp enters t-he recess 7L in the lock-case, it has a long bearing therein, and the lid is prevented from shifting backward or forward or toward either side relative to the body. Hence the hinges which secure the lid or cover to the body are relieved ot' injurious strains. back of the lock-case F is secured a loekingbolt of novel construction. It consists of a bolt-plate, G, which is hinged at one end in the locl -case,and has near the other end a bolt projection, working through a hole, i, in the back of the recess 71, and adapted to engage with a cavity, i?, in the hasp. The plate G might be hinged in the lock-case by a pinlle or rod; but as here shown the lock-case has a slot or opening, j, in one edge, and the end of the plate enters this slot or opening and has an angular lip, j', which forms the hinge-point. In lieu of being hinged, the plate G might be so iitted in the lock-case as to be capable of a bodily sliding movement forward and backward. \Vhen hinged, the plate G can swing back at the upper end only. When not pushed back, the plate G is held in its forward position, with the projection t' presented through t-he back of the recess h, as shown in Fig. l1, by a spring, 7.1, one end of which enters a cavity, 7.a', in the plate, and the other end of which bears against the back plate F ot' the lock-case.

In lieu of a spiral spring, a spring applied in any other way may be used for a like purpose.

The bolt-plate G has a hub or boss, 7, to receive a key, and which projects through an opening, l', into the recess 7L.

rlhe hasp I) is bifurcated or forked at the lower end, as shown in Fig. 2, and when it enters the recess it straddles the hub or boss Z,- hence the hasp has a longer bearing on the lock-case than it otherwise would have.

As shown in Fig. l, the front of the bolt projection i is inclined, and when the hasp enters the recess 7L it pushes the projection and the plate G inward until the cavity t2 is opposite the projection, whereupon the latter moves outward and engages with the cavity. The hasp is released by pressing the linger on the hub or boss 7 to move the bolt-plate and In the recessed' projection G i inward, and hence, when not used as a lock, the parts form a snap-catch for a valise or trunk.

H designates a guard, which slides in a dovetailed slideway, m, on the front of the hasp, and which may be slid up to expose the hub or boss Z, or down to cover the same, as shown in Fig. l. rIhe same screw, f', which secures the spring j" to the hasp D,enters a groove` f2, in the guard H, as shown in Figs. l and 2,and limits its upward and downward movements. In the back of the bolt-plate G are two dovetailed slideways` a o,which are at right angles to each other. The slideway a has fitted to it a slide or tumbler, a, which works across the bolt-plate, and in the slideway ois iitted a stop, o', which works upward and downward on said plate, so as to cause its point to engage with or withdraw from notches in the edge ofthe slide or tumbler a. rlhese parts are shown clearly in Fig. 4.

I designates a U-shaped spring, one end of which is fast in the bolt-plate G,and the other end of which engages with the stop o,and, the slideways fn. o being dovetailed, this spring holds both the tumbler and stop a o in the plate G. In the slide or tumbler a is a hole or cavity, of, and on the back plate F is a pin, a. (Best shown in Figs. l and 5.) This pin is also shown in Fig. 4 to show its relation to the hole n2 in the slide or tumbler n, although in said figure the back plate, F, is removed. A key inserted through the hub or boss Z enters the cavity Z2 in the plate G, which accommodates the wards of the key and raises the stop o to disengage it from one of the notches ofthe slide or tumbler n, and then shifts the slide or tumbler so as to bring the hole o1? opposite to the pin n, or to carry the said hole away from a position opposite said pin. to bring the hole ai opposite the pin or. as shown in Fig. 5, the trunk is unlocked and the bolt-plate G may be pushed in to with draw the bolt projection t' from the cavity i" in the hasp; but when the slide or tumbler is shifted into'the position shown in Fig. 4 the pin is not opposite the hole and the bolt-plate cannot be pushed inward because of the solid metal of the slide or tumbler a striking against the said pin a, hence the said pin forms an abutment to prevent the inward movement of the bolt-plate G, and thus locks the latter against movement. j

Obviously the pin a and hole n2 might be reversed in position, the pin being on the side or tumbler a', and the hole being in the back plate F; or an abutment of any other form might be employed to prevent the inward movement of the bolt-plate G when the slide or tumbler n is moved into a locking position.

The several parts of the lock may be made of cast-iron, malleable iron, or steel, or of other metal.

Vhat I claim as my invention, and desireto secure by Letters Patent, is-
